To aZZ 507101211 time concern; t Be it known thatI, JOHN YOUNG, a

citizen of the'United States, residing in the 'ci't'y and county of San Francisco and State oifCalifornial'have invented certain new and f useful In proi'emen'ts' in Apparatus for Y ting andDepositing"Ring-Liners onto the Flanges of can-0 m of which thefo'llow ing is a specifieation'if c The presentinvention' relates to means for" intermittently feeding a web of paper,cutting therefrom a ring liner, ositioning 'a' can coifer with relation to the cutting me'c'hanisi nyand forcing the -ring"liner onto the flange of the can cover; the object 'o'f'the invention being the production of a simple,

efficient and durable machine for the cutting of ring liners; bythe-"cuttingjor' die punch; of Which not only serving to cut the ring liners, butto place the cutliner' ontothe flange of the can cover, the die, punch thus performing the double fnnctio'flof cutting the ring liner and forcing-the sa-ine as one.

I operation onto the flange of" the cover and by so doing enablingthe carrier means for the covers and cut ring liners and the parts associated therewith for placing the ring liner relative to the flange of the cover'to 'be dispensed with.

To comprehend the invention reference should be had to thea'ccompanyi'ng sheets of drawings, wherein 1 Figure 1 1s a vertical sectional viewof the linproved apparatus, taken in l1ne'a2''m Fig.2 of the drawings, disclosingtheposi tion of the die punch,' .the'inean's' foractiiat ing the same, theposi'tion' of the web relative to the die punch and the can cover to receive the ring liner cut from theweb, and the means for feeding can covers into position beneath the die punch. Fig. 2 isa front ele ration of the apparatus partly'insectio'n, i p the feed runway for the can covers being" removed, said View illustrating the means for actuating the feed control for the'iveb from which the ring liner isstamped.

In the drawings. the numeral 1 is used to designate any suitable form of a support ing frame for sustaining the werking parts of the apparatus, which frame is provi'ded or spindle 2Q situated atone fside through the feed rollers 21, 22, ann 3;

the rollers 2l and'23 being held in fri with 'an upwardly extended rearwardly incline'd head block Qcarrying a bed plate, 3. \Vithin the head block2 ismounted for recipiocating movementa punch block 4, car-- ryingthe spaced die punches 5 and 6. [The punch block has reciprocating motion iin parted thereto by means of a cam' 67" on the drive shaft 7 engaging With the rolls Sand to' one end of the driveshaft, the said shaft I at its' opposite end portion having attached thereto a cam grooved disk 10. In the cam groovel'l of said disk Works a roll. 12 Se cured 'to afstud 12 projecting from the-up per end portion ofa' lever 13 fulcrumed to" the head block 2; the lower end of said lielf being pivotally connected to one end of .a slide rod 13 Working'in guides of the said head block 2 and being piv'otally connecte'd;

at its opposite end to a crank arm 14: up{ wardly projecting from a shaft 14 for afctu ating the hereinafter described mechanism for imparting a step feed 'movementfto'the I Web 15 from which the ring liners arecut;

To the bed plate 3 is attached immediately over the punch opening 15 the' die ring 16',

with which coacts the punch 5 for cutting acircular opening 16' in the web' 15 of a di ametere'qual to the'inner diameterhfvthe ring liner to be cut therefrom,- and sai'd'bed plate'is also 'proi 'ided with a countersunk a for the reception of the canflhead rcover 17: delivered therein through slotted opening18 from theifeed chute or runway 18". The seat l7is in line with andIi nme diately under the .die punch '6, wlnch 's off a Y:

diameter slightly larger thantha tfotthe punch 5 and on its downward incitement cuts" from the web 15 the ring liner l9 forces. V

The web 15, cut to the desired containedon'a spool 19 mounted ong a stud:

machine frame, and the said Web'i's boxes 2-1 for said rollers slidably mounted. .1

in the guide brackets 25. On the shaft 25. for'the roller 22 is secured a gear 26, in mesh with a gear 26?, which said gear has an intermittent or step rotation imparted thereto pawl 27 on the crank arm 14 which pawl is in locked engagement with the said gear 26' on each down stroke of the crank arm 14;. This crank arm is thrown up and down through the action of the slide rod 13, which is reciprocated back and forth by the fulcrum lever '13 through the medium of its roll 12 working in the cam groove 11 of the disk 10'. The motion of the feed roller 22 is transmitted to the feed roller 23 by means of a sprocket chain 22 working on the sprocketwheels 23 on the shaft for the said rollers 223l'ld23/f',

The can covers 17 are held 'within the chute or runway18' by the stop pins 28 and 28' which are downward projections of the fulcrumed lever 29, and by the stop'pin 29' depending from a bracket 30 secured to and forwardly projecting from the punch block, 4, and which at its outer end carries adepending stud "30 for actuating or tripping the lever 29, the pin 28 of which is" carried by the overweighted end thereof. The movement of these stop pins is such that covers 17 held thereby are released one at" a timewithin the inclined chute orrunway' 18, the lowermost cover ofthe series when released by the upward movement of the sto pin 29' passing through the opening 18 lnto'the seat 17 of the bed 3, being held thereinby the stop pin 31 against passing outwardly through the discharge. openin 32. This stop pin 31 is normally held'upward by the spring held lock-bolt 32 acting against the block 33 through which the stop pin 31 is extended. p 7

On the downward movement of the cross head 9 the punch head block 4 moving there-t with, the stud'30 of the bracket 30 bears against the upper end of the fulcrumed lever 29, forcing downward the stop pin 28 and raising the stop pin 28, thus releasing a can cover 17 and allowing the same to move downwardly by gravity until engaged by the stop pin 29 placed within the runway 18 by the downward movement of the punch head block 4. On the upward stroke of the said punch head block the outer end of the lever 29 is released, and the stop pin 1 28' moves downwardly withinthe runway 18' to check the flow of the'can cover, while the cover released by the upward movement of 'thesto'p 'pin 29" moves into. the seat 17 throughtlie opening 18 until arrested by the stop'pin31. H v .t

As the punches 5 and '6' aremovedwith the downward movement of the punchhead' block, the punch 5 cuts a eircular hole 'indicated by a from-the web 15, while the'die punch -6 of slightly increased diameter acts on the web where-previously perforated by the punch 5 and cuts therefrom a ringliner 19, which cut or severed ring liner is forced downwardly. by the die :punch 6 into 'the for driving the roller 22 by means of the:

seat 17 and onto the flange 17 of the can cover 17.- The die punch 6 thus cuts the ring'linerfrom the web 15 andforce's-the same onto the flange of the cover 17 as a single opera'tion,"the'web 15 remaining stationary over the bed plate 3 duringthe cutting action of the punches 5 and 6. K

Owing to the space existing between the punches 5 and 6, the punch 5 is required to make one perforation of the w'eb l5 before I the same 'is presented to the action ofthe cutting die 6, so'by the'time one ring liner. is cut from the web there will be three per-.

forations in that portion of the web within the machine, those made by the punch 5 be ing represented by the letter a'and the perforation of increased diameter made by the die punch '6 being represented by b+-Figl 3 of the drawings;

.The s'top pin 31 is l owe red as the punch downward movement by the shouldered port-. tion 34 of a ,U-shaped (spring 34: secured to and carried by the sai punch head block head block 4 approaches the limit of its l moving into engagement with the projection 35 of the collar 33 and forcing the same down until the top of the pin 31 clears the outlet or discharge opening 32, in which po; sition it remains until the die punch 6 moves,

out of the seat 17, so as to allow the can cover with its applied liner ring'to slide' by gravity out of said seat through the discharge opening 32, after which the shoulder 35 engages withfthe projection 35 and raisesthe stop "pin 31. The spring held slide bolt 32, gives inwardly on the downward pressure exerted on'thev p'in3l', but the momentlthe same is raised'to place the collar 33'clear of the slide bolt, the same springs outwardlyto. hold the stop pin in locked position.

On the-upstroke of the punch hea d block I the lever 13 is operated to force outwardly.

the slide rod 13", which throwing downwardly the crank arm ltcarrying the pawl 27 'in locked engagement with the gear 26 imparts a part rotation to said gear, which A I through thedescribed interconnected parts operates the feed rollers 21-22 and 23-23,

to' 'advance the web 15 a given distance With-1 in the machine to place a perforation 2 thereof beneath the die pi1nch 6 andan uncut surface beneath the diepunch 5. v

The mechanism for controlling the feeding' of the web through the machine is throwninto action bythe upward or return movement of the die plungers, the same re- .maining' at rest on-thedownward stroke; of y I the saldplungers the various working parts w re of the apparatus being so timed. relative to eacho'ther as to come'into successive action at predetermined times.
